Abstract

An N x N crossconnect switch, for large N, is implemented using an arrangement of smaller wavelength routers combined with space switches. An N x N
crossconnect switch is constructed in three stages, using a plurality of input space switches, a plurality of (N/m) x(N/m) router (whose reduced size N/m allows efficient realization in integrated form), and a plurality of output space switches. In the router, the number of wavelengths is reduced by a factor m. The input and output space switches can be implemented using crossbar or Clos type construction. In one arrangement each modulator is combined with a small space switch consisting of 2 x 2 elements. Each space switch can be realized with negligible crosstalk by using a dilated arrangement.
